The Production Process of 3-AMINO-N-CYCLOHEXYLBENZENESULFONAMIDE

The production process of 3-amino-N-cyclohexyldibenzene sulfonamide, also known as CCB, is a complex and multi-step process that involves several chemical reactions and purification steps.
CCB is a derivative of benzene and is used as an intermediate in the production of dyes, pigments, and other chemicals.
In this article, we will take a closer look at the production process of CCB and the various chemical reactions that are involved.

Step 1: Production of N-Cyclohexyldibenzene Sulfonamide
The first step in the production of CCB is the production of N-cyclohexyldibenzene sulfonamide, also known as N-CHDBSA.
This is achieved by reacting cyclohexyldibenzene with a sulfonamide precursor, such as chlorosulfonic acid, in the presence of a solvent like acetonitrile.
The reaction is exothermic and requires careful temperature control to avoid unwanted side reactions.
The resulting product is a sulfonamide intermediate that is further purified by filtration and washing.

Step 2: Production of 3-Amino-N-Cyclohexyldibenzene Sulfonamide
The next step in the production of CCB is the reaction of N-CHDBSA with an amine, such as aniline, in the presence of an acid catalyst, such as hydrochloric acid.
The reaction is carried out in a solvent such as water or a mixture of water and an organic solvent like methanol.
The resulting product is 3-amino-N-cyclohexyldibenzene sulfonamide, which is also known as CCB.
The reaction is typically carried out at a moderate temperature, and the product is purified by filtration and washing to remove any remaining impurities.

Step 3: Purification of CCB
The purification of CCB is a critical step in the production process, as it ensures that the final product is of the required purity and quality.
The purification process involves several steps, including filtration, washing, and recrystallization.
The filtered and washed CCB is dissolved in a solvent such as ethanol or methanol, and the resulting solution is allowed to cool slowly.
The crystals that form during cooling are collected by filtration and washed with additional solvent to remove any impurities.
The resulting crystals are then dried and weighed to determine the yield.

Overall, the production process of CCB involves several chemical reactions, purification steps, and quality control measures.
The various steps involved in the production process of CCB require careful monitoring and control to ensure that the final product is of the required purity and quality.
The use of high-quality raw materials and the implementation of sound manufacturing practices are also critical to the production of CCB.
The production process of CCB is complex and requires the use of specialized equipment and facilities, making it a challenging process to master.
However, with the right expertise and resources, CCB can be produced in a safe, efficient, and cost-effective manner.
